There are a lot of good ones out there. One of my all time favorites, and I'm not sure if it is still in print, is "The Third Saturday in October" by the late Al Browning. It is a history of the Alabama-Tennessee rivalry, game by game. Eli Gold has a new one talking about his years broadcasting at Alabama. I've not read it, but its probably worth the trip to the book store just to skim through it. Jay Barker has a good one, and John Forney as well.
